It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
In view of the above-mentioned technical problem of large brightness difference between different display regions, the present embodiment provides a display control method, please participate in fig. 1 to 3, as shown in fig. 1, which includes the following steps:
Step S10: the configuration display area comprises a first display partition and at least one second display partition.
It should be noted that, the display area may correspond to the entire display area of the single display screen, and at this time, the display area is a partial display area of the single display screen; the display area may also correspond to an entire display area formed by splicing a plurality of display screens, and in this case, each display area may correspond to a display area formed by one or more display screens.
Step S20: and judging whether the difference of the display parameters between the first display partition and at least one second display partition is within a preset range or not.
It should be noted that, the display parameter difference may include a brightness difference and a display area where the brightness difference is located, the brightness difference between the multiple display areas may be photographed by a camera to obtain original data of a corresponding image, where the original data may include brightness and coordinates of sub-pixels, then different display areas are defined by the coordinates of the sub-pixels, then average brightness of each display area is obtained by distributing brightness of each sub-pixel in the corresponding display area, and finally brightness difference between the corresponding display areas, that is, brightness difference of the display area, may be obtained by comparing average brightness of the different display areas. The distribution area of the sub-pixels with the brightness difference in a certain range can be determined through the coordinates of the sub-pixels, and then the size of the display area with the brightness difference can be obtained according to the distance between the sub-pixels.
Step S30: if not, the initial brightness of the corresponding display partition is adjusted so that the difference of the display parameters between the first display partition and at least one second display partition is within a preset range.
The average luminance may be referred to as an initial luminance before the adjustment by the present display control method, and the average luminance may be referred to as a target luminance after the adjustment by the present display control method. The target brightness may have a plurality of different values, however, it is understood that no matter what the values are, the brightness difference between the different display areas is reduced by the display control method.
It can be appreciated that, in the display control method provided in this embodiment, when the difference of display parameters between the first display partition and the at least one second display partition is not within the preset range, the initial brightness of the corresponding display partition may be adjusted so that the difference of display parameters between the first display partition and the at least one second display partition is within the preset range, thereby reducing the difference of brightness between the corresponding display partitions and improving the uniformity of brightness of the display area.
In one embodiment, the display control method further includes: constructing the initial brightness of the first display partition as target brightness; if not, adjusting the initial brightness of the corresponding display partition so that the difference of the display parameters between the first display partition and at least one second display partition is within a preset range, specifically including: if not, the initial brightness of at least one second display partition is adjusted to the target brightness.
It should be noted that, in this embodiment, the initial brightness of the first display partition is taken as the target brightness, and then the brightness difference between the different display partitions is reduced by adjusting the initial brightness of at least one second display partition to the target brightness. The method reduces the number of display areas needing to be adjusted in brightness, and is beneficial to reducing the workload required by brightness adjustment.
In one embodiment, the step of constructing the initial luminance of the first display section to be the target luminance further includes: judging whether the brightness uniformity of the first display partition accords with a preset uniformity range or not; if not, adjusting the brightness uniformity of the first display partition to enable the brightness uniformity of the first display partition to accord with a preset uniformity range.

In one embodiment, the display control method further includes: constructing preset brightness as target brightness, wherein the preset brightness is different from the initial brightness of the first display partition or the initial brightness of at least one second display partition; if not, adjusting the initial brightness of the corresponding display partition so that the difference of the display parameters between the first display partition and at least one second display partition is within a preset range, specifically including: if not, the initial brightness of the first display partition and the initial brightness of at least one second display partition are adjusted to the target brightness.
It should be noted that the display area may be the display area AA shown in fig. 2, the first display area may be the display area S1 shown in fig. 2, and the second display area may be at least a part of the display area S2 shown in fig. 2. The distribution of the display area S1 and the display area S2 is not limited to that shown in fig. 2, and may be other various distribution forms, for example, the area of the display area S1 may be equal to that of the display area S2, the display area S2 may surround the display area S1, or the display area S2 may include a plurality of second display areas.
It should be noted that, in this embodiment, the preset brightness is taken as the target brightness, and then the brightness difference between the different display partitions is reduced by adjusting the initial brightness of the first display partition and the at least one second display partition to the target brightness. In the method, the initial brightness of all the display subareas which are inconsistent with the preset brightness is required to be adjusted, and when the initial brightness of at least one display subarea is consistent with the preset brightness, the number of the display subareas which need to be adjusted can be reduced, so that the workload required by brightness adjustment is reduced.

It should be noted that, in this embodiment, initial brightness adjustment may be performed on at least one display sub-area in the first display partition and at least one second display partition. For example, with the target brightness as a reference target, the initial brightness of at least one display subarea in the first display subarea or the initial brightness of at least one display subarea in the at least one second display subarea may be adjusted; the initial brightness of at least one display subarea in the first display subarea and the initial brightness of at least one display subarea in the at least one second display subarea can be adjusted simultaneously, and the adjustment speed of brightness uniformity can be improved by the bidirectional adjustment mode.

It should be noted that, in this embodiment, each display sub-area may include at least one sub-pixel, and the average brightness of each display sub-area may be achieved by adjusting the brightness of at least one sub-pixel in the display sub-area. That is, the average brightness of each display subarea can be independently regulated and controlled, so that the required brightness of each display subarea can be rapidly and accurately realized, and the speed and the precision of the brightness uniformity among different display subareas can be improved.
In one embodiment, the step of "determining whether the difference of the display parameters between the first display partition and the at least one second display partition is within the preset range" specifically includes: judging whether the brightness difference between the first display partition and at least one second display partition is within a preset brightness difference range; and/or judging whether the ratio of the area of the continuous area where the first display partition and the at least one second display partition with the brightness difference within the preset brightness difference range and the total area of the display partitions is within the preset area ratio range.

In one embodiment, the display control method further includes: configuring a plurality of display partitions including a first display partition and at least one second display partition; constructing the initial brightness of at least one second display partition as target brightness; judging whether the area of the area corresponding to the brightness difference between the first display partition and at least one second display partition is within a preset range; if not, the initial brightness of the first display partition is adjusted to the target brightness.
In one embodiment, the display control method further includes: configuring a plurality of display partitions including a first display partition including at least one first display sub-area and at least one second display partition, each second display partition including at least one second display sub-area; judging whether the area of the area corresponding to the brightness difference between the first display partition and at least one second display partition is within a preset range; if not, the initial brightness of at least one first display subarea and/or the initial brightness of at least one second display subarea are adjusted so as to control the brightness difference between the first display subarea and at least one second display subarea and the area corresponding to the brightness difference to be in a preset range.

It should be noted that, the embodiment provides a specific adjustment method for the brightness of each display subarea, where the average brightness of the display subarea can be improved by increasing the light-emitting current and/or the light-emitting time, so as to improve the average brightness of the display subarea where the display subarea is located; conversely, by reducing the light emission current and/or the light emission time, the average brightness of the display subarea can be reduced, thereby reducing the average brightness of the display subarea where the display subarea is located.

It should be noted that, the preset brightness difference range may be set reasonably according to the brightness difference that can be identified by the human eye, and may also be set comprehensively by referring to at least one of the observation distance from the human eye to the display area and the area size of the display area.
In one embodiment, the display control method further includes: configuring a preset brightness difference range to be more than or equal to 0 and less than or equal to 0.5; the preset area ratio range is configured to be greater than or equal to 0 and less than or equal to 0.5.
